Title: Learning Randomized Reductions and Program Properties for Security, Privacy, and Side-Channel Resilience (PhD dissertation defense)
Abstract:
Modern computing systems face multifaceted challenges in security,
privacy, and leakage resilience. This dissertation makes four key
contributions to addressing these challenges. First, it focuses on
analyzing side-channel vulnerabilities in low-level cryptographic code
and quantum computers using symbolic AI techniques. I introduce novel
symbolic register analyses to automatically detect power side-channel
vulnerabilities in constant-time cryptographic implementations.
Additionally, I demonstrate an algebraic reconstruction method to
reverse-engineer quantum circuits from power traces, aiming to extract
proprietary information from these circuits. Second, my research
explores learning randomized reductions. Informally, a randomized
self-reduction allows computing a function’s value at a specific point
by evaluating it on randomized inputs. Here, I present a new framework
that dynamically infers such properties from implementations using
machine learning. Third, the dissertation demonstrates practical
applications of these randomized reductions in compiling effective
countermeasures against power side-channel and fault injection attacks.
It also develops protocols for leakage-resilient machine learning and
private quantum computations. Finally, it investigates learning-based
methods for partitioning propositional encodings of combinatorial
security analysis problems within the cube-and-conquer paradigm, which
splits large SAT instances into smaller, more tractable subproblems. We
train transformer models to learn branching heuristics within
SAT-solving frameworks. Together, these contributions advance automated
security analysis and resilience across classical and quantum domains.
